低比特图像压缩的 matlab实现，主要是游程编码-Matlab low bit image compression to achieve, mainly RLE

游程编码是一种简单的非破坏性资料压缩法，其好处是加压缩和解压缩都非常快。-RLE is a simple non-destructive data compression method, the added advantage of very fast compression and decompression. The method is to calculate the length of consecutive compression of the data.
